... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...

Super Rocket Targets . NPO MOLNIYA has been designing rockets-targets for over 30 years using the great experience in crea-ting anti-aircraft guided rockets (AGR) for C-25M. On the basis of B-300 anti-aircraft rockets which expired their service life, there were designed, tested and put into the serial production the following types of the rocket - ... The analogue of this system successfully passed the state tests with the ZVEZDA-4 rocket-target. ...
